Title: Astable high frequency integrated circuit multivibrators - consist of two AND gates with two other elements to give good performance
IPC: H03K3/03
Filed: 1968-11-15
Abstract: Two simple multivibrator circuits using simple AND gates and very few additional components are suitable for integrated circuit construction. Both circuits give good operation up to several megahertz, with square wave outputs, the first producing a 1:1 mark space ratio, and the second a selection of mark space ratios up to 10:1 according to component choice. Both circuits are insensitive to temperature and supply voltage variations. The first arrangement consists of two AND gates coupled together using one capacitance and one resistance. A square wave output is produced. Other inputs to the AND gates are used for the application of logical signal, preventing or permitting the circuit to oscillate. The second circuit is similar but contains two capacitances and two diodes, allowing a mark to space ratio to be determined by selection of these component values.

Title: Gas cooker burner assembly - is pot and lid type with grooves in lid underside with slit extensions for slower, flame stabilising jets
IPC: F23D14/06
Filed: 1969-10-07
Abstract: The burner for a gas cooker is basically conventional with a 'pot' plenum chamber closed by a removable one-piece 'lid'. The gas flows through radial grooves between the two; in some of these flow is slowed down to ensure flame stability. These grooves (4) are formed in the lid (2) which has centering lugs (3) locating it in the smooth-edged pot (1). In the top of each groove there is an extension (5) of smaller cross-section and the lid rim (6) is turned down to partially enclose an annular space (7) into which these extensions debouch. High efficiency combustion of the gas is obtained, and the lower velocity stabilising jets prevent flame failure due to lift off.

Abstract: The car seat hinge has a friction adjustment of interlocking cone surfaces which are operated axially. A square section shaft (9) has a set of inner cones (13,14) sliding axially on it ball races (17) and acts against internal friction cone surfaces on an outer element (11). This provides infinite rake adjustment with a secure hold. The ball races are held in cut-outs so that the contact faces between the balls and the cone body are more than just a point contact. Alternately the inner cone can slide on the shaft on profiled bores and the ball races can be mounted in blocking cages between the cones.

Title: Clamping mechanism for slip coupling - disc shaped holding cage is spring supported with stops to prevent overrun
IPC: F16D41/02
Filed: 1973-04-19
Abstract: The coupling is for transmission of an intermittent rotary movement between two shafts. The clamping or retaining mechanism cage (7) is pressed against the driven shaft by compression springs. Overrun with consequent wear on the clamps is reduced thus achieving a precise amount of slip. The spring force is controlled by a ratchet mechanism and the cage (7) together with the driven shaft (5, 6) have bosses (12) that prevent excessive relative movement. The cage (7) is disc shaped and has clamping rollers (11) held by bolts (10) fixed round its circumference. The bosses are rod shaped (12) and these fit loosely in holes in the cage disc. At the same time the rods act as holders for the tensioning springs.

Patent JP-H0442967-B2 (JP)
IPC: B29B11/08
Filed: 1985-02-05
Abstract: This relates to laminated preforms, the method of forming such preforms and products which may be beneficially formed utilizing such preforms. Most particularly, this relates to a preform which has formed as part of the injection molding thereof two layers of barrier material which are disposed within two layers of thermoplastic resin and having received therebetween a solid core of thermoplastic resin. The specific method of forming the preform permits the barrier material layers to be of a greatly reduced thickness as compared to such layer tick- nesses permissible in the past, with the result that the barrier material layers in the blow molded articles are of a thickness recognized to be acceptable for the barrier function. The barrier material layers may be selectively terminated along the length of the preform so as to permit portions of the resultant blow molded article to be removed and reused.

Granted: 1998-12-16
Abstract: A rigid three-dimensional preform is made by moving a plurality of webs of fibrous reinforcement material superposed and coplanar to a cutter, the webs being coated with an electromagnetic energy-curable binder and pressed together. Prior to cutting a blank in a two-dimensional development of the three-dimensional preform from the webs, the webs are tacked together at spaced local zones by locally curing the binder at those zones by locally applying the appropriate electromagnetic radiation (microwave, ultraviolet, electron) so that the webs travel as one to the cutter. After cutting of the blank, the blank is loaded into a mold to replicate the three-dimensional shape of the preform and the remainder of the binder is cured in the mold by the application of the appropriate electromagnetic radiation. An auxiliary member may be attached to the preform by applying an electromagnetic energy-curable binder to at least one location on the preform, moving the auxiliary member into a desired position and intimate contact with the binder-coated location and the binder cured at that location by the application of the appropriate electromagnetic radiation.

Granted: 1997-11-19
Abstract: This invention relates to a photomagnetic recording method for writing data into a photomagnetic medium by using a magnetic head whose magnetic field is modulated by a recording signal and an optical pickup. In accordance with the present invention, a first data pit group is first recorded on the photomagnetic recording medium with gaps greater than a predetermined data pit recording gap and then each data pit of a second data pit group is recorded between the adjacent data pits of the first data pit group. A photomagnetic recording apparatus according to the present invention can cope, by interleaving write method, with both the factors of frequency characteristics of the magnetic head and the thermal interference of adjacent pits that limit high density recording or high speed access, and can accomplish both high density recording and high speed access.

Patent JP-S6232796-B2 (JP)
IPC: G10L13/02
Filed: 1979-04-27
Abstract: A speech synthesis circuit is provided with a variable frame length data converter and the speech synthesizer is preferably integrated on an integrated circuit chips. The variable frame length data converter reduces the amount of data required to synthesizer human speech at a given quality level. Preferably, a full frame of data includes, a pitch parameter, an energy parameter, a repeat bit and a plurality of speech coefficients. Each parameter or coefficient has a preselected length, but each frame has a variable number of parameters or coefficients associated therewith. The parameters and coefficients are encoded and a particular code of the pitch parameter indicates that the speech is to be unvoiced. An unvoiced frame includes fewer coefficients that a voiced frame and the converter detects this particular pitch parameter and automatically sets the unsent coefficients to zero. The converter also detects the state of the repeat bit for controlling the synthesizing to use the coefficients received during the previous frame as the coefficient to be used to generate speech in response to the present frame. In this embodiment, when the repeat bit comes up, new pitch and energy parameters are inputted therewith. Further, the converters preferably detects particular codes in the energy parameter for determining when a pause occurs or when the last frame of data has been sent.
